 * @date      12/23/2009
 * @brief     STM32F10x Medium Density Devices Startup code.
 *            This module performs:
 *                - Set the initial SP
 *                - Set the vector table entries with the exceptions ISR address
 *                - Initialize data and bss
 *                - Setup the microcontroller system.
 *                - Call the application's entry point.
 *            After Reset the Cortex-M3 processor is in Thread mode,
 *            priority is Privileged, and the Stack is set to Main.
